vBe it known that 1.I-IARRY B.-SMrrH-, a citizen of the United States,residing at New York, Y

. invention', such as will enable others skilled in the art to which it appertains yto make and use the same.

This invention .relates to a gage for making vpaper boxes, and especially designed for applying the extended bottoms of boxes to the body of 'thelatterlv There is at present a large demand in the trade for paper boxes having extended bottoms-that is to say, boxes havingfbottom's that extend or project laterally on `all sides a slight distance beyond the sides and ends of the boxes, against which the b ottom edges of the tops or covers of the boxes seat.. In the'manufacture of such boxes it has been the practice to first form the body of vthe bo'x and then secure to the bottom of such body by means of paste or other suit-- ableadhesive the extended bottom, consist-i I slightly-greater dimensions'in each direction,

so that the extended bottom when secured in place projects laterally beyond the sides and' end l of the box. Heretofore such bottoms have' been'seeured 'to the box-bodies by hand, the operator having nothing to guide Ahim in thel operation but the eye, and for this reason the manufacture of such boxes has been islow; laborious, and unsatisfactory, resulting in'imperfectly-eoustructed boxes at a relatively-large cost.

It is the object of the present invention to provide a gage by means of which the extended bottoms of the boxes may be applied to the box-bodies with absoluteaccuracy and uniformity and with great rapidity; and it alsoihasforjits object to make `the gage adinstable in such manner that Ait will aecomrtiodate boxes of dipferent sizes an'd shapes It has lfor a still further object to provide 'a gage of the character. described in which the different adjustments can be quickly and easily made and which shall Vbe simple and inexpensive in construction and effective and the extended bottoms to be applied to the boxbody blanks before the latter are folded up into shape, whereby theboxes maybe shipped or stored in aflat condition in readiness to be bent up and secured' into shape Vfor use.

` .To these ends my invention consists in the features and in the construction and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims following this descriptiomreference being a part of this specification, wherein- Figurel is a top plan View of my improved device, showing an extended bottom and boxblank 'in place therein. Fig. :lis a longitudinal section thereof. Fig. 3 is an enlarged plan view, partly in section', of one of the .taken on the line 4 4 of Fig. 3. y f

Referring to the drawings, the numeral l indicates a base or platform, which may, if desired, be in the form of a table and is provided with a longitudinal slot- 2. -upon the opposite ends o f the base or platform fare twoadjus table gages, and inasmuch as said gages are duplicates one of the other the construction of one only of them need be described, and is as follows. Thev numeral 3 indicates the bed or bottom of the gage, consisting ofa flat plate resting upon the platforml and having two flat and vertical flanges or sidesl 4 which intersect eachother at a right angle. The bed 3 is adj ustably secu red to the platform 1 by a headed bolt 5,-which passes through the slot 2 and through a bolt-hole formed in the bed, and has screwed over its upper threaded end a thumb-nut 6. AIt is obvious that when the nut is loosened the bed may be moved laterally or longitudinally upon the platform and when adj usted to the desired position may be locked in place by screwing up the nut. Formed in the faceof each of the vertical. sides or flanges 4 is a horizontal groove 7, in which is movably fitted a corresponding rib 8, formed onlthe rear side of a iiat guideplate'9. The guide-plates are thus movable toward and from each other at a right angle, and their adjacent rvertical edges are preferably cliamforcd or beveled, as at 10, at an .'anglo` of approximately forty-five degrees.

accurate in operation andwhich `will permit gages; and Fig. #l is avertical sectional view' Disposed ing had to the accompanying drawings,'form IOO 2 y assess' Projecting rearwardly from each of the ribs 8 is a threaded stud or bolt 11, which extends through a horizontal slot 12, formed in the adjacent side or flange 4, and screwed over the rear end of said stud -orbolt is a nut 13,

rear 'edge of the side or iangeand is engaged l. by an adjusting-screw 15,' the inner end of- `which is unthreaded and passes .through a 'suitable perforationform'ed in thecor'responding stud or bolt 11 and is held in place therein vby a' pin or key 1G ,passed transversely through the -end of the' adjlasting-screw..` It will be evident that by turning the 'adjustingsscrews in one direction lor theotherv the adjacent beveled edges of lthe -gnideplates will be moved toward or from each other for the purpose hereinafterexplained. y

The operationl of 1n l improved gage isas follows', it'being premised that in the manufacture of paper :boxes the body of the box is usually/formed' from a blank 'similar to that shown in Fig. 1 of the drawings, wherein theL numeral 17 indicates the bottom of ,the boirbody,18 the'side flaps, and 19 the end iaps, which are respectivelyadapted to be folded up vertically at right anglesto the bottom 17 on the scored lines 20, and the numeralj21l indicates the extended outer bottom. Toy prepare .or place the devicein readiness for attaching y toms to the box-body blanks,

the extended big the thumb-nut 6 are loosened and the two gages are adjusted at` such a distance apart l that when a boX-blank'is placed between the two gages in such manner that thelatter will i *A "fit-'within the notches at the two diagonal opi l" posit@ 'corners of the blank the facesof the f guide-platesQ Will loosely engage the adjacent end edges ofthefsid'e and end flaps 18 and-19, sufficient play' or' clearance being provided l t'opermitIihe `ready insertion yand removal f Ioff the'blank-betweenthe'ga-ges.

are also adjusted laterally about'th'eirbolts nn'tilthe faces of the guideplates areexactly parallel with the adjacent 'end edges of y the side and end iaps'of the-boxblank. After these adjustments 'have been'effectedthe nuts 6` are tightened up to locky the gages lliri'nlyjin their adjusted positions. lr.[jlheguide'#plates:I9 of eachgagefare .then 'adjiist'ed at 'such distance :apartthat when' one of the extended bottonis' 21 is placed ,betvtfe'euy the gages the j two diagonal-1y 'corners of the bottom'pwill prof ject between the two guidef-platesof eaclrgage 'and WillV snugly fit the beveled edgesof said v guideplates Infusing the device the operai `tor first' places one of the extended bottoms 21 between' the gages and"4 then inthe same manner plac'esa bon-blank upon the topof the extended bottom, 'paste or other-adhesive having been 'iirstalnjliedy to either the extended bottom or to the bottom of the box-blank.

This operation is successively repeated until as many bottoms and box-blanks have been arranged between the gages as the heightiof The eases tive of the size of the boxesand the faces of' the guide-plates will in all eases accurately engage and lie parallel with the end edges of the side and end iiaps of the box-blanks.. lf

is obvious, however, that when it is desired to make a box o f oblong shape' or 'of unequal Width and length it ivilhbe necessary to make 'provision for adjusting the gages laterally as well as A'longitludinally, for it will be apparent that'the guide-plates' would not in such case accu rately engage and lie, parallel to the end edges of the `side and end .iiapsot the box- .blan'k, andyhence the gages have to be shifted laterally to. one side or 'th/e other of thecentral'slot and. to a greater or less extent, dependent upon the size of the box-blank. This is accomplished lby loosening the nuts 6 andl turning the gages about the bolts 5 as centers and then tightening up the nutsin the manner before described. l l l 'Itwill be apparent thatone of the gages may be 'affixed to Vthe platform or bed so as to be incapable of being adjusted longitudinally,- and while I Vprefer to make both gages longiloo."

tudinally'adjnstable' I Wish'it to be 'understood that linelude both arrangements when I'refer to the gages as vbeing 'longitudinally adjustable toward eael'lfother.I It Will also be 'apparent to" those skilled in the -art y that the construction jand arrangement of parts maybe varionslylaltered", modified, o'r changed Y Without depart ing fro n1 the spi rit of myfinvention, andjthi`s is'e'specially true lotthe' means employed for effecting inentsofthe partsjfz,l
